Recently bought a Gap IID tool for my 2006 V6 LR3. Now thinking about lifting it 2.5 inches using the Gap tool, and swapping on 275/65/18 tires. Garage at work has 6’3” of clearance so I’ll probably need to use access mode with the lift and larger tires.

Will i run into issues with this tire size in access mode? If so, is there a way to program an increased access mode height using the Gap tool that would work here? (Or other possible solutions?)

 

Yes and yes.

You can save up to 3 height settings. Maybe target one that is in between Access and Normal; just low enough to allow clearance. I run 275/65R18s as well and if in Access Height (stock settings) I can go straight but if I turn more than say 5 degrees, I'll rub.

If you plan to raise the height with the GAP tools and leave it in the modified settings all the time, then your "new Access height" should be fine since it will effectively be a little higher than stock-Normal height.

 

Perfect, thanks for the input there.

Seemingly unrelated question: there's an issue with the brake switch on these trucks, I've had a couple go out over the past 13 years of ownership. No big deal currently, I just keep an extra switch in the console. But when this happens, the suspension lowers. With a programmed lift, does anyone know if suspension would lower to the new access height, or to the bumpstops in cases where this brake switch goes bad? Just want to be prepared if the bigger tires rub w/more than a slight turn and a bad brake switch sends the truck to its bumpstops.

 

Brake switches are a known issue. Ford part, ,alternative Ford branded switches can be less than LR branded. Not sure if a switch failure means it will drop for sure, but if there is a fault bad enough for the EAS to lower it will go to the stops.

Keep in mind any major adjustments to the suspension will of course require an alignment if you plan to run at new heights all the time.

 

As an FYI, you can only set a max of 52-53mm on the base height setting since off road selection adds another 50mm on top of that.
So 1) might be lower than normal height then 2) +25mm and 3) +50mm.

 

The brake switch failure goes to Access Height, not bumpstops.

It wouldn't be fun, but it would be survivable if that happened with 275s on.

Last June I was wheelin' and got in a bad situation with my 275s stuffed into my wells....and mine are bigger than most because they are Coopers and run big (32.6")...anyway I ripped out the wiring loom for the EAS, and you know what the result was??

Suspension fault, Adaptive Headlight fault, and wonky 4x4 info display. That's it. Everything still worked. EAS, Terrain Response, everything. I continued wheelin all the next day, then drove home 200 miles no big deal. Then rebuilt the **** out of that wiring loom with stainless steel braided mesh and SS zip ties. 😁

Point being we tend to over-think this stuff. Get the tires!

 

Guilty as charged.

Thanks again!

 

Helpful info, thanks. Is +52mm enough to accommodate 275/65/18s?

 

Did some more research on other forums, people have reported success with even a 30mm base lift and this tire size. Programmed it in and getting them installed as I type.

 

I should have mentioned that that's the size I run.
